Abstract

The utility model discloses a spider king jointed board for developing intelligence and improving the ability of brain thinking. The utility model comprises a base plate and jointed blocks composed of small blocks which are cut from a group of analog equilateral polygons. One group of equilateral polygons have the same centers O, parting lines are arranged between the center O and the midpoint m at each side of the equilateral polygon, between the center O and a crossing point p, and between the two adjacent polygons. The utility model has the advantages of reasonable structure; the utility model can be assembled into variety Chinese characters, geometric figures and animal and plant patterns, and assembled patterns have a beautiful and regular appearance. The utility model brings fun to children during teaching, and can particularly culture learning interest.

Description

Spider king jigsaw

One, technical field

The utility model relates to a kind of intelligence jigsaw, specifically a kind of spider king jigsaw of similar cobweb formula.

Two, background technology

The intelligence jigsaw can be developed people's intelligence, impels people's brain development, improves people's thinking ability.Jigsaw puzzle all is made up of some jigsaw with given shape.For example, the seven-piece puzzle of generation of being popular in becomes the especially toy liked of children of people already, and it is made up of seven jigsaw such as triangle, square and parallelogram.Present jigsaw type toy is mainly used in picture arrangement game, and what have also can assembly organize some arabic numeral, letter and Chinese character, as child and children's puzzle, carries out the body cognition training.Existing jigsaw type toy shortcoming is: 1, jigsaw is of a great variety, complex geometry, and every kind of jigsaw piece number is few, and risk near figure in kind has big difficulty, true to nature, standard and quick that the arabic numeral of particularly risking, letter and Chinese character can not be accomplished; 2, for risking various figures, often need to buy more dissimilar jigsaw, the expense height.

Three, summary of the invention

The purpose of this utility model provides the spider king jigsaw that a kind of geometric configuration is simple, can risk various figures true to nature.

The purpose of this utility model is achieved like this: a kind of spider king jigsaw, comprise substrate and piece, it is characterized in that: described piece is made up of the fritter that is divided on one group of similar equilateral polygon, this group of equilateral polygon has identical central point O, is provided with cut-off rule T between the mid point M on central point O and each limit of equilateral polygon and intersection point P; Equilateral polygon mid point on one side is provided with the cut-off rule A that is connected with previous similar equilateral polygon intersection point; The mid point of polygon adjacent edge is provided with the cut-off rule B of preceding second similar equilateral polygon intersection point connection and the intersection point of previous equilateral polygon and is provided with the cut-off rule C parallel with this cut-off rule B.

On the one hand for risking various required patterns, requirement has more little piece, on the other hand, for reducing manufacturing cost, be convenient for carrying and preserve, in line with economical and practical principle, the quantity of little piece is unsuitable again too many, in the utility model, described one group of similar equilateral polygon is four equilateral octagons, has 136 fritters.Distance between described adjacent two similar equilateral octagons reduces from outside to inside gradually.

Compared with prior art, the utility model is rational in infrastructure, form by the little piece that the lines of a plurality of similar equilateral polygons and similar cobweb are split to form, select for use the little piece of some can be combined into any numeral in 0～9, also can be combined into any English letter among A～Z, can also be combined into various Chinese characters, geometric figure and animals and plants pattern, it has wide range of applications, the pattern rule that is combined into and attractive in appearance.Its advantage is: people are used one's brains, give full play to one's imagination, risk various images, lively pattern, be of value to physically and mentally healthy; 2, can teach through lively activities, help children's tap intellectual resources, cultivate child's learning interest.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2, Fig. 3, Fig. 4, Fig. 5 all are user mode figure of the present utility model.

Five, embodiment

A kind of spider king jigsaw described in the utility model comprises substrate 1 and piece 2.Piece 2 is made up of 136 fritters 3 that are divided on four similar equilateral octagons totally, and these four equilateral octagons have identical central point O, is provided with cut-off rule T between the mid point M on central point O and each limit of equilateral octagon and intersection point P; Equilateral octagon mid point on one side is provided with the cut-off rule A that is connected with previous similar equilateral octagon intersection point; The mid point of octagon adjacent edge is provided with the cut-off rule B and the previous equilateral octagonal intersection point that connect with preceding second similar equilateral octagon intersection point and is provided with the cut-off rule C parallel with this cut-off rule B.Distance between adjacent two similar equilateral octagons reduces from outside to inside gradually.In an equilateral octagon near central point O, only be provided with the mid point M on central point O and each limit of equilateral octagon and the cut-off rule T between intersection point P.

The utility model can satisfy all ages and classes level crowd's demand, is particularly suitable for cultivating child's learning interest with helping children's tap intellectual resources.In the picture mosaic process, can select different fritters as required, give full play to the imagination of oneself, risk any numeral in 0～9, perhaps be combined into any English letter among A～Z, can also be combined into various Chinese characters, geometric figure and animals and plants pattern.

Claims
